摘要：本文分析了磴口52年(1954-2005)逐月降水量、蒸发量及相对湿度。结果表明:60年代降水量、蒸发量、相对湿度均偏大,70年代降水量、蒸发量、相对湿度均偏小。90年代降水量偏大,蒸发量偏小而相对湿度偏大,近5年降水量偏小,蒸发量最大,相对湿度反而偏大。降水量与蒸发量均为夏季最大,冬季最小。而相对湿度则是夏秋季相近,春季最小。降水量与蒸发量夏季波动形式与年的波动形式比较相近。
According to the date of precipitation and evaporation and specific humidity in Dekou oasis since recent 52 years, the changes were analyzed. The results showed that precipitation, evaporation and specific humidity were bigger in 1960s, but they were smaller in 1970s. Precipitation and specific humidity were bigger, but evaporation was smaller in 1990s. Precipitation was smaller and evaporation was bigger but specific humidity was bigger in recent 5 years. Precipitation and evaporation was the most in summer, the smallest in winter. Specific humidi- ty in summer was as same as in autumn. The fluctuation of precipitation and evaporation in summer was basically coincided with annual precipitation and evaporation.
